Executive Summary

Large engineering organizations and distributed teams routinely lose weeks of productivity bringing new hires up to speed: onboarding for nontrivial codebases commonly ranges from 2–8 weeks and consumes significant mentor time, contributing to a roughly $15.0B addressable market based on 25M developers spending about $600/year on onboarding and tooling. The product I’d build is an AST-driven LLM agent platform that pairs robust program-analysis (AST, type graphs, call graphs, lightweight symbolic execution) with specialized LLM workflows to generate reproducible dev environments, targeted walkthroughs, automated first PRs with tests, and provenance-tracked explanations tied to code structure. Delivered as cloud and on-prem options with IDE, Git, and CI integrations, the agents would prioritize verifiable transformations and test-backed suggestions so teams can measure reductions in time-to-first-merge and mentor hours—conservatively targeting a 30–50% improvement in early ramp metrics in initial pilots. This moment is attractive because large pre-trained LLMs have reached practical accuracy for code when constrained by program analysis, remote hiring growth increases demand for self-serve ramping, and many orgs already allocate ~$600/developer/year to tooling, so adoption and willingness to pay exist. To stand out versus medium-competition incumbents (Copilot/Sourcegraph-style assistants and generic LLM toys), the product must lean into AST-first correctness, reproducible devflows, enterprise privacy (on-prem/self-hosting), and measurable ROI rather than chatty help. The core challenges are nontrivial engineering complexity across languages and build systems, maintaining freshness against evolving repos, and earning enterprise trust with audits and deterministic verification, but if executed well this approach can meaningfully reduce hidden onboarding costs and create a defensible enterprise foothold.

Executive Summary

Market Opportunity

Solve slow codebase onboarding with AST-driven LLM agents targets a $15.0B = 25M developers x $600 annual onboarding/tooling spend total addressable market with medium saturation and a year-over-year growth rate of Developer tools: ~8% CAGR; AI-enabled dev tooling: ~25-35% YoY.

Key trends driving demand: AI-for-code -- LLMs plus program analysis enable higher-accuracy code understanding and generation; Remote engineering teams -- distributed hires increase onboarding costs and demand for self-serve ramping; Shift-left dev practices -- teams want earlier, automated dev environment setup and reproducible devflows; Knowledge consolidation -- monorepos and polyglot stacks create need for programmatic mapping of code intent.

Key competitors include Sourcegraph (Cody), GitHub (Copilot, CodeQL, Code Search & Codespaces), OpenAI + LangChain / LlamaIndex / Tree-sitter (DIY LLM stacks), Stack Overflow for Teams / Enterprise Knowledge Bases.
